there is a different between bein' happy and pretendin' to be..

Everytime I think of you my heart stops, well it's not that stop that makes me gonna die, but it's that stop that makes me breathless.Everyone who knows me would notice, but to be true, there is no one who did.
Everywhere I go I pretend to be 'the happy girl', 'the lovly girl' or 'the sweet girl'.. Everyone believes me.I pretend to be me, I pretend to be happy.
